26/08/2025 - Update to Proposal Plan published. This will be presented to the REC Change Panel at their meeting on 02 September 2025.
Summary
Non dual-fuel Consumers who register upon the PSR, will have their PSR data flow across energy industry data flows to mean that all parties are aware of any PSR Needs Codes, allowing us all to provide equal access to our services and support. This will be achieved via the utilisation of existing processes and systems. Initially a pilot will take place for a minimum of 3 months between participating companies before extending this to the whole industry”.

Problem Statement
The majority of domestic customers in the UK are what are called in the industry ‘dual-fuel’ - this means that with two types of energy (electricity & gas) a domestic dwelling has a single supplier ie they pay their bill to one organisation. This ‘dual-fuel’ position has supported the industry improvements to Priority Services Register (PSR) data flows by allowing previous divides to be overstepped in terms of data flows between energy types. There is however a problem which this RECC request aims to resolve. That is, where a customer who has both fuel types, also has two suppliers and they want to register upon the PSR. This was always a ‘known’ gap shared with our regulator when the many improvements were implemented across the PSR and considered to be something that would be addressed at a later date. This ‘gap’ means that without the dual-fuel link, currently data flows do not complete across energy types via the supplier data flow triggers.

Latest Update
18/11/24 - The Authority has approved R0182 for Implementation. R0182 will now be targeted for an extraordinary release on 08/12/24.
Summary
This Change Proposal seeks to introduce the necessary governance and charging amendments to existing Payment Method Levelisation (PML) Reconciliation arrangements (introduced in R0147) to allow for multi-register reconciliation. The amendments will allow for an ongoing reconciliation that accounts for split in both single-rate and multi-register Metering Assets. Additionally, it will also allow for a one-off retrospective recalculation for the period dating from the proposed effective implementation date of 01 January 2025 back to the implementation of the original reconciliation mechanism on 01 April 2024.

Proposed solution summary
- N/A – No identifiable Consumer impact.
- M1 - As a Domestic Supplier, I want my PML Reconciliation payments to be as reflective of my portfolio as possible, by differentiating between single rate and multi register Metering Assets, so that my engagement with the reconciliation is as accurate as possible. M2 - As a Domestic Supplier, I want my PML Reconciliation obligations regarding the retrospective recalculation to be well defined within the REC, so that I am able to engage as efficiently as possible. M3 - As RECCo, I want the PML Reconciliation mechanism to be reflective of REC Parties true costs (based on their single-rate vs multi-register split in their portfolio), so that I am able to deliver the most optimised outcome for PML Reconciliation participants.

Problem Statement
PML Reconciliation currently does not distinguish between single-rate and multi-register electricity Metering Assets. This represents a discrepancy, as Price Cap methodology currently does make this distinction. As a result, PML Reconciliation calculation methodology must be updated to distinguish between single-rate and multi-register Metering Assets. This will be effective for all reconciliations going forward from the date of implementation, as well as retrospectively from the start of the PML Reconciliation in April 2024, to the date of implementation.

Proposal for Limiting Queries in EES API Calls (Single Query per API Call)

Urgent
No
Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
This issue has been raised proposing to establish a limit on the number of queries permitted within a single Application Programming Interface (API) call. As there is potential for performance degradation and system instability that can occur when a large number of queries are made in a single API call to the Electricity Enquiry Services (EES) API. The aim would be to prevent overwhelming the system and ensure consistent response times and reliability. Therefore, this proposes implementing a limit of 1000 queries per single API call.

Problem Statement
The absence of a limit on the number of queries (batch processing) within a single API call could cause performance issues and system instability. As a result, system responsiveness may degrade when a large number of queries are made in a single call, impacting user experience and hindering the ability of the EES API to consistently meet user demands.

Problem Statement
Reported inconsistencies in the application of elements of the entire new connections process result in poor Consumer outcomes. Whilst the new connections process spans multiple processes owned by different Codes, the REC Code Manager is conducting an exploratory initial analysis, owing to our place as a dual-fuel, Consumer facing Code. This analysis is expected to yield multiple modifications across multiple Codes that will result in improvements to the new connections process.
